OK, back to Alice's mission. Her plan has changed a little and she will now first stop in the region of Alpha-C (AC) for some observations. It is way too late to achieve the rocket braking at the original very low (0.075g) acceleration, so Alice asked her INS computer to get them into a 'parking' orbit at a more comfortable 1g retro-burn. Her INS and my trusted spreadsheet 'know' that at -1g, it will take 0.69 years to get the coasting ship to zero velocity relative to Bob, and that it must start to brake 0.2 lyrs (on their rotated map) short of the parking position. At just over 11 years into her mission, Alice comes to rest in Bob's spacetime structure again.

During the 0.69 years of deceleration, Alice's tilted structure has gradually rotated back to align with Bob's structure once again. While their structures were at an angle to each other, space and time were different for them. Here is a summary of the space and time accounting columns:

As Mitchell has indicated above, there is a slight possibility that a future super-dooper technology could perhaps bring Alice back home with the amount of fuel that she has left. As we also discussed, if you have the technology, a higher acceleration would be better, so let us look at a one earth gravity (1g) setting ...

I have been receiving what seems like an inner "guiding hand" to very specific scientific subjects. Not hearing voices or anything lol. Quantum physics, time travel, nanotubes, nanobots, chemtrails, and other subjects. Before 2 years ago I did not know some of these things existed, and I certainly didn't know how they worked. And now I somehow guide myself through some sort of pre existing science and biology curriculum of which I am my own nutty professor. I am in no way complaining. Just hopelessly interested in everything I read about with an insatiable thirst for knowledge??? Has anyone else experienced a sudden heightened scientific enlightenment with no explanation??

Not long ago I found myself spending a few days of holiday down near Southend on the Essex coast. One afternoon we climbed up the hill to visit the ruins of Hadleigh castle which stands overlooking the railway line and the Medway marshes of the Thames estuary. Built in 1215 by Hubert de Burgh in the reign of King Henry III, the castle was substantially rebuilt a century later by Edward III as part of the Medway defences against the French during the Hundred Years War. Edward III in fact made it his principal residence outside of London for much of his reign.

Little remains of Hadleigh castle today. It was built on an unstable outcrop of London clay and developed an unfortunate habit of collapsing at unexpected moments. Large quantities of the fallen stonework were sold and carted off in the Tudor period, you can still see the tiled hearth where the wreckers melted down the valuable window leads. John Constable painted an atmospheric...
